A German frigate was at moorings in Copenhagen on Monday (September 29) to assist with airspace surveillance after NATO said it was upgrading its mission in the Baltic Sea in response to the situation in Denmark.

The frigate FGS Hamburg was docked in Copenhagen after arriving on Sunday, with passersby stopping to look at the vessel at its moorings.

France, Germany and Sweden said on Monday they will send military personnel and anti-drone systems to Denmark to boost security at this week's European summits in Copenhagen, after drone incursions that forced Denmark to shut several airports.

Denmark is due to host EU leaders on Wednesday, followed by a summit on Thursday of the wider, 47-member European Political Community. It has already said it has increased security around the events after the drone sightings.

Drones disrupted air traffic at six Danish airports last week, including at Copenhagen, the Nordic region's busiest, in what Prime Minister Mette Frederiksen called a hybrid attack on her nation.
